Goldman Sachs-backed battery storage developer GridStor has acquired a 200MW/800MWh project in Oklahoma, US, from Black Mountain Energy Storage (BMES) to bolster the electric grid’s resilience and reliability.

The battery storage project will be developed in two phases and is expected to address the urgent need for new power resources identified by the Southwest Power Pool (SPP).

The project coincides with the SPP’s call for additional power resources to be operational by 2030, a measure to support electric system reliability amidst rising energy consumption from data centres and industrial customers.

The project will be developed in Eastern Oklahoma, close to multiple operational data centres, with more under construction.

GridStor CEO Chris Taylor said: “Battery storage is a scalable and near-term solution to provide reliability to the SPP system and its large customers.

“Batteries provide energy to stabilise the power system and meet hours of greatest demand every day in multiple regions across the US. This acquisition demonstrates GridStor’s commitment to rapidly adding battery energy storage to the SPP grid to support the growing needs of its residents and businesses.” 

GridStor’s latest transaction signifies its second project acquisition within the past year, underscoring the company’s growth trajectory and efforts in integrating battery facilities with American power infrastructure.

These facilities are essential for storing electricity and ensuring its availability during peak periods.

Black Mountain Energy Storage CCO Witt Duncan said: “As a developer of utility-scale energy storage projects nationwide, BMES is pleased to support GridStor in their endeavour to support emerging grid needs with utility-scale battery storage.

“Together with GridStor, we’re building reliable, affordable, and sustainable energy solutions today for a promising tomorrow.”

In October 2024, GridStor started construction of its 220MW/440MWh battery facility in Galveston County, Texas. The Hidden Lakes Reliability project, previously known as Evelyn Energy Storage, is set to commence operations by mid-2025.
